Air Shower Room And Cargo Shower Room

Application

Air shower is the necessary purification equipment for personnel to enter the clean room and dust-free workshop. It has strong universality and can be used with all clean rooms and clean workshops.

It can reduce the pollution problem caused by people entering and leaving the clean room. The two doors of the air shower room are electronically interlocked, which can also act as an air gate chamber to prevent external pollution and unpurified air from entering the clean area. Prevent the staff from bringing hair, dust and bacteria into the workshop to meet the strict dust-free purification standards of the workplace.

Structure

1. The air shower room is composed of several parts, such as box body, stainless steel door, high efficiency filter, air blower, distribution box and nozzle.

2, the box is made of high quality steel plate, surface electrostatic treatment, beautiful and generous, the inner bottom plate is made of stainless steel plate friction resistance, easy to clean.

3, the main material and dimensions of the box body can be customized according to customer requirements.
